If you’re reading this, it’s likely that your computer has suddenly become slow. You looked in the Task Manager (CTRL+SHIFT+ESC) and noticed that spoolsv.exe was utilizing nearly all of your CPU. That’s bad enough, but it’s considerably worse. If you have no idea what process is running or how to fix Printer Spooler Service High CPU Usage in Windows 10 & 11. Here are a few pointers to get you started.
First, let’s figure out what is running the spoolsv.exe process on your computer. Normally, spoolsv.exe is a process associated with the Windows Print Spooler Service. This service is an important part of your printing. Because it allows you to print documents in the background without interfering with other operations. When your printer is running, the spoolsv.exe service should appear in the Task Manager. If it isn’t, highlight spoolsv.exe and click End Process.
However, malware may masquerade as spoolsv.exe at times. It will appear in Task Manager as the legitimate service, but you can tell if it’s malware by inspecting the file’s path. The actual Spooler Service file is typically 61,440 bytes in size and should be located in the percent SYSTEM percent subfolder. If you suspect that the spoolsv.exe process is being run by malware, immediately scan your computer with your security suite and remove anything it finds. This malware may be responsible for 100% CPU usage as well as a slew of other errors.

Regardless of how little your processor is, the Spooler service is not a resource-intensive activity that should overwhelm your computer.
When you look in Task Manager and see that the service is utilizing up to 100% of the CPU, logic dictates that there are too many print jobs waiting to be completed in the spool.
Due to system difficulties, completed print jobs can get stuck in the spool.
You almost never have too many queues to the point where the spool becomes overburdened. The only plausible scenario is if there is a system flaw that prevents completed print jobs from being automatically cleared from the queue. This implies that the computer will keep allocating memory and resources to tasks that have previously been performed, overworking the CPU and depleting your RAM.
The Microsoft Office image writer’s printing jobs were backed up:
The Print Management folder is a nice place to look for all print jobs that are currently queued for printing. To get there, use the navigation string below: Print Management may be found under Control Panel > Administrative Tools > Print Management.
You can see all of the print jobs that are currently queued in the Print Management folder. The folder will also show you how many print jobs are queued on each of the printers installed on your printer.
Virus or malware:
There’s always the risk that a virus or malware has attacked your machine. If you can’t figure out what’s generating the strangely high spooler CPU utilization.
In some Windows OS versions, the Spooler service has been discovered to be vulnerable to security flaws.
A worm reported to be linked to this issue is known to ingeniously disguise itself by registering with the identical spoolsv.exe process name. It is critical that you install capable Internet security software as soon as possible. Clean your computer and eliminate this threat before it spreads and does even more harm.

A Quick and simple workaround:
A slow computer may be a major inconvenience as well as a productivity killer. Fortunately, most issues are simple to resolve. As previously stated, if you currently have an anti-malware application installed on your computer, this is the signal that you need to beef up your protection and update it or install a stronger one.
However, one can consider simply terminating the spoolsv.exe process in the task manager. While this may provide some respite, it isn’t a long-term solution because you will eventually need to print certain documents. Stopping the spoolsv.exe process in Task Manager while documents are printing or are still printing will also stop the printer.
When the printer queue won’t clear, or while you figure out what’s causing the spooler’s high CPU utilization, printing straight to the printer is a workaround. Simply choose it from the print options menu.
Too many outstanding jobs might cause the Print Spooler to utilize a lot of CPU in Windows 10, which can put your operation to a halt. Check to see if any of the files are still in the queue, even if they were completed. You may wish to reinstall the printer and install the most recent drivers. Because malware might create this problem, it’s never too late to invest in a good antivirus.
Hopefully, the options shown here have assisted you in resolving the spooler’s excessive CPU utilization issue. If the problem persists, you should always seek advice from a professional, especially before making any modifications to the Windows registry.
